A polymer is formed of ethylenically unsaturated monomers including a zwitterionic monomer, an aromatic monomer and a cross-linking monomer. Preferably the crosslinking monomer includes at least one a group containing compound and at least one aliphatic group containing compound. The polymer is water-swellable and a hydrogen has optical and mechanical properties rendering it suitable for use as an intraocular refractive device such as an intraocular lens.
